4said ymeans comprises a. table 17 (Figs. 3

and (l) guided 'for `vertical movement by means ot pins 1S fixed to said table and e2;- tending slidably through bloc-ks l) Xed to brackets E() that are rigidly attached to the side. members El and ll. wWhen the table is in its lower position it rests upon the blocks l). On the side edges f the table 17 are flanges or'rihs 2l to prevent lateral displacement of the bottoni (I. When the bottom is resting upon the table 17, the down-turned end flanges (Fig. 5) of the bottom lie at opposite ends of the table and prevent endwise displacement of the bottom. means herein Shown for raising and lowering the table 17 consists ot' a hand lever 22 pivoted on a shaft 23 mounted in the side members 3 4, said lever having an arm :24: which has a Apin and slot connection with lugs 25 on the table 17.

In the embodiment herein shown, means is provided for unlocking and locking the bottom (l, which means consists oi" an angular hand lever 26 pivoted at 27 to the table 17 and provided with two lugs 28 adapted to lie at opposite sides @fone ot' the projections i 'j on the locking bar f.

A magazine filled with bobbins to be cleaned having been placed upon the seat provided therefor on the side members 3 il, the operator depresses the lever 22 to raise the table 17 into contact with the bottom ci, the lever 26 occupying a central position7 z'. e., so that its body portion extends parallel with-the locking' bar f. The raising of the table 17 brings the lugs 2S on the lever 26 at opposite sides of a projection j on the lockingr bar f. Holding the table l? elevated, the operator swings the lever 2G to one side or other of its central position, thereby withdrawing the ends of the barf 'from the slots g, and thus releasing the bottom (Z from the magazine. The table 17 may now be lowered with the bottom .'Z resting thereon.

Directly below the magazine seat on the side members 3 and 4. is a support tor a magazine to receive the cleaned bobhins. ln this iembodinient said support comprises two rails 29 lifted to the lower side oi the table 2 and adapted to support a magazine by its upper 'frame Z).

30 is a stop to determine the operative position of the magazine. Vlhere is an. opening 3l (Fig. 5) through the table 2 directly above the support ior the receiving magazine. vertically alined with the partitions in said magazine are balsI 3Q (Figs. and 6) extending between the side members and l.

The means 'tor feeding bobbins from the upper magazine to the cleaning means and The o moe for moving the cleaned bobbins to a position above the receiving magazine comprises, 1n

.fixed on the shafts 23 and Si) which are cari'ied in l'iearings on the side members 3 11nd Ll. flhe bearings for the. shaft 35 are adjustable, as shown in Fig. il, to permit of takinnn up slack in the chains. chains 25? C54 are lugs 3G which form between them recesses to receive the bodies of the bobbins. lt will be understood that the form of these lugs may be varied to suit -the shape of the bobbins to be carried. The upper runsl of the chains 83 34 are supported upon the brackets 20 and areheld from sidewise displacement by flanges 37 (Fie. 7) on said brackets andv by,plates 38 that are ixed to the brackets Q0 and overlie'angular portions on the lugs 36. Said plates also prevent the upper runs of the chains vfrom jumping` upwardly. The lower runs of the chains are prevented from sagging by rails 39 and are herd against upward displacement by rails 40, the rails 39 and 40 being` fixed to' the brackets 20. While being moved by the upper run of the conveyer, the boh- -bins ride upon the flanges-l'?. TWhile passing around the sprocket wheels on the shaft 35, the bobbins are ffuded by twoy curved guides ll (Figo) which are continued to form rails l2 on which the bobbins ride until they reach the first bar 43 areconverging` guide plates which serve to shift the bobbins longitudinally as the conveyor moves, and thus act to bring the bobbins into uniform position on the conveyer. The plates are continued in the retaining plates 44 which extend at both sides of the path o' movement of the bobbins from the guides 43 to the 'arthermost bar 32. 44a is a guard plate to prevent accidental upward displacement of the bobbins.

ln the present embodiment of the invention, the operation performed upon the bobbins is the removal of waste yarn, lint or other material from the bores of the bobbins, the clearing;- of the bobhins beingl effected, in the particular embodiment herein illustrated, by forcing" the material out ol the boreby a blast of pressurefluid, such as compressed air. rl`he pressure fluid may be obtained from any suitable source. llerein l have shown an air compressor comprising a cylinder having; trunnions l-G 47 journaled in bearings in the machine 'frame l. ln said cylimler is a piston 118 connected by a rod 4.() to a pin on a crank plate 50 (Fig. the latter being fixed upon the drive shaft 5l. Said drive shaft is herein shown as provided with a drisewvheel The intake or suction valve for the cvlinder 45 is indicated at 53 in Fig. S. he liseharge takes place through a passage -ler;-
